Flex Circuit Products
Bare flex circuits in every common construction, plus assemblies with connectors and SMT components, built to your drawing from prototype to mass production.
Bare board flex circuits
Every flex circuit we make is built on polyimide with rolled annealed or electrodeposited copper. Choose the construction that matches your routing density and how much the circuit needs to bend.
Single-sided flex circuits
One conductive layer, either bonded between two insulating layers or left uncovered on one side.
Single-sided circuits are the thinnest and most flexible construction, which makes them the best choice for dynamic flexing, tight bends and cost-sensitive designs.
Double-sided flex circuits
Two conductive layers with an insulating layer between them, plus cover layers on the outer layers.
They can be made with or without plated through holes (PTH). Plated through holes connect the two layers, so you can route more signals in the same area.
Multilayer flex circuits
Three or more flexible conductive layers with flexible insulating layers between each one, interconnected by plated through holes.
Multilayer flex handles complex, high-density designs with separate signal, power and ground or shielding layers. We build up to 8 layers.
Multilayer rigid-flex circuits
Rigid and flexible substrates laminated together into a single package and electrically connected by plated through holes. Outer layers may have covers or exposed pads.
Unlike a flex circuit with stiffeners, rigid-flex has conductors on the rigid layers, and the plated through holes run through both the rigid and the flexible layers. That removes connectors and cables between boards.
Assemblies
Save time and assembly cost by receiving your flex circuits ready to install. We offer hand placement and soldering, SMT, reflow and wave soldering.
Flex circuits with connectors
Flex circuits delivered with connectors already assembled, surface mount (SMT) or through hole (THT), to save you time and lower your cost.
SMT component assembly
SMT components assembled directly on the flex circuit, with stiffeners where parts need support, as a complete turnkey solution.
Options for every application
Every product above can be built with the stiffeners, surface finishes and shielding your design needs. See our capabilities for the full list of materials and tolerances.
- Stiffeners in FR-4, polyimide, polyester, steel, aluminium or copper
- Immersion tin, ENIG, electrolytic hard or soft gold, immersion silver and OSP finishes
- EMI shielding with solid or crosshatched copper, conductive silver or aluminium
- Acrylic adhesive or adhesiveless constructions
